| 摘 要： | 为了掌握海南岛冬种瓜菜苗期湿涝灾害的发生规律，减少灾害损失，保障农业生产。从影响海南岛冬种瓜菜苗期湿涝的天气和地表环境出发，综合考虑降水强度、次数、雨后乍晴等气象致灾因子和地势、地表覆盖类型、表层土壤质地等孕灾环境因子，进行了湿涝灾害风险区划。结果表明，海南岛冬种瓜菜苗期湿涝的高风险区主要分布在东部和北部部分地区；西北部地区为湿涝中风险区，主要包括：儋州、临高大部分地区以及澄迈、海口北部地区；中南部以及西部地区发生湿涝灾害的风险相对最低。该区划空间分辨率高，对合理作物布局、提高冬种瓜菜种植的安全性等具有重要意义。

| Abstract: | In order to understand and master occurrence regularity of waterlogging disaster in winter vegetables, to reduce disaster losses, and to ensure the grain production, a winter vegetable seedling waterlogging disasters risk zoning was done by taking the effects of weather and earth＇s surface environment integrated into account in this study. For weather, the intensity of precipitation, number of precipitation process was taken. And earth＇s surface environment, topography, land cover, soil texture was saw as risk pregnant environment. Hainan island winter vegetables seedling waterlogging high-risk areas mainly in the eastern and northern parts; northwestern region, and little part of northern was moderate waterlogging risk zone; central,southern and the western region of occurrence of waterlogging disaster risk was relatively low. The zoning had a high spatial resolution and useful to crop layout and enhance the security of planting winter vegetables. |
